Conductive carbon black

Product Description

Conductive carbon black is carbon black with low or high resistance. It can give products conductive or antistatic effects. It is characterized by small particle size, large and rough specific surface area, high structure, clean surface (few compounds), etc.
(Carbon black) is a kind of carbon black that uses its own conductive properties, high structural properties, irregular aggregates, and very small nano-scale size, easy to mix with other materials, etc. It can form a three-dimensional network structure conductive path in insulating plastics, rubber inks, and paints, so that the insulating products have conductive functions under the action of conductive carbon black, so that the insulating materials have antistatic and conductive capabilities.

Auxiliary Materials Industry knowledge

Auxiliary materials play a crucial role in the production of rubber, plastic, and other manufacturing processes, providing essential support and enhancing the performance, efficiency, and cost-effectiveness of primary materials. These materials are not the main components of a product but are critical for modifying properties, improving processing efficiency, and ensuring the quality of the final product. In industries like rubber, plastic, coatings, and adhesives, auxiliary materials are used to assist with formulation, processing, and performance optimization.

Key Categories of Auxiliary Materials
Plasticizers:

Plasticizers are substances added to materials like rubber and plastics to increase their flexibility, workability, and processability. By reducing the viscosity and improving the flow characteristics of polymers, plasticizers make the material easier to mold or extrude into different shapes.
Common Plasticizers:
Phthalates: Widely used in flexible PVC applications.
Adipates: Used in products requiring low volatility and high thermal stability.
Citrate esters: Employed in medical and food-grade products for safer formulations.
Fillers:

Fillers are materials added to rubber, plastics, and other compounds to modify their physical properties, improve processability, and reduce costs. Fillers can improve the strength, hardness, durability, and other characteristics of the final product.
Common Fillers:
Carbon Black: Used in tires and rubber products for reinforcement and UV resistance.
Calcium Carbonate: Increases volume and improves the mechanical properties of plastics and rubber.
Silica: Often used in tires to reduce rolling resistance and improve fuel efficiency.
Curing Agents and Vulcanizing Agents:

Curing agents or vulcanizing agents are chemicals added to rubber compounds during the manufacturing process to promote chemical cross-linking, which transforms the rubber into a more durable, elastic, and heat-resistant material.
Sulfur is the most common vulcanizing agent for natural rubber.
Peroxide curing agents are used for certain synthetic rubbers that require more heat-resistant properties.
Other vulcanizing agents include zinc oxide, magnesium oxide, and accelerators to speed up the vulcanization process and control the cross-linking reaction.
Stabilizers:

Stabilizers are used to protect materials from degradation during processing or prolonged exposure to environmental conditions such as UV light, heat, and oxygen. They help to maintain the integrity, color, and performance of the product.
Common Stabilizers:
Antioxidants: Prevent the oxidation of rubber and plastics, improving aging resistance.
Antiozonants: Protect rubber products from ozone degradation, particularly in outdoor applications.
UV stabilizers: Used in outdoor applications, such as in automotive parts and construction materials, to prevent UV-induced degradation.
Lubricants:

Lubricants are used during the processing stage to reduce friction and improve the flow properties of rubber or plastic compounds, making them easier to handle in extrusion, molding, or injection processes.
Processing Oils: These lubricants are added to facilitate the processing of rubber, such as aromatic oils or naphthenic oils, which can reduce the viscosity and enhance the material's workability.
Internal Lubricants: These include agents like stearic acid and fatty acids, which are added to prevent sticking and improve the processing efficiency of the material.
Pigments and Colorants:

Pigments and colorants are used to add color to rubber, plastics, and other materials. They help enhance the aesthetic appeal of the product and are essential for branding, product differentiation, and visibility.
Organic Pigments: Offer vibrant, long-lasting colors for applications such as consumer goods and automotive parts.
Inorganic Pigments: Provide durability and stability, used in industrial and outdoor applications, such as in construction materials and automotive coatings.
Flame Retardants:

Flame retardants are chemicals added to materials to reduce their flammability or delay the onset of combustion. They are crucial for enhancing the safety of rubber, plastics, textiles, and coatings used in industries where fire safety is critical.
Halogenated Flame Retardants: Provide efficient fire resistance but may present environmental concerns.
Non-halogenated Flame Retardants: These are newer, more environmentally friendly options used in electrical cables, construction materials, and automotive applications.
